Limit Table of Contents to a chapter

Hi,
I don’t understand why limit table of content to a chapter automatically works only for chapter level 1.
here is my doc style :

  • Title, level 1
  • H1 level 1
  • H2 level 2

And the structure :
#Title
#H1
ToC (limit to a chapter, disable plan mode, enable extra style) work fine and automatically. Here I put title from level 2 to 4.
##H2
ToC (limit to a chapter, disable plan mode, enable extra style (title from 3 to 6)). This does’nt work automatically. It takes Title level 3,4,5,6 for all the document, not just for the chapter.
###H3
####H4

####…

H3

H2

I don’t understand :frowning:

H3
